Warranty Process

2. Remote troubleshooting.
   
3. Determine the cause of the issue.
   
4. Provide replacement parts or replacement products if covered under warranty.
   

Most technical issues can be diagnosed remotely without returning the product.

Depending on the situation, this may include:

• Wiring harnesses
  
• Other service parts
  

This approach minimizes downtime and reduces international shipping costs.
